Checking For A Failed Drive
Getting slow performance?....lots of hard drive activity when nothings running?...copy/move commands coming up failed due to read only...you might have a failed drive. However before you toss the drive out you can do some hard drive checks.
Perform a SMART system testOpen the "Disk Utility" under the MENU->ACCESSORIES menu in Linux Mint XFCE, and look at the SMART results or perform a test
If you dont have that you can run the test via command line. The following examples will use /dev/sdb as the hard drive to test, replace with your drive of choice. first install the required packages.
Check if smart is enabled:
If not enabled, enable it:
Run a health test:
Or a extented health test
If a failure is listed this will give more detail:
Check The FilesystemFirst unmount the filesystem
Run a check on a EXT4 filesystem:
If using EXT2/3 File Systems use:
Check The Filesystem AutomaticallyAutomatically all debian based systems will check the file system every X reboots. You can see exactly after how many time your system checks via:
Look for ""mount count"" parameter. Usually 32 I beleive. You can change this to howevery manu you want, replace X with how many boot ups to check.
Check The The Hard Drive For Bad Blocks
If you get any bad blocks from this command showing you can try to fix it and mark the spots but your best bet is to back up your date (WHICH YOU DO REGULARILY RIGHT?) and replace it.
